Overview

The Mersen C1037509 is a single-pole, open-design fuse-base engineered specifically for gPV photovoltaic fuse-links in size NH2, optimized for high-performance solar applications. This robust unit is rated for a continuous current of 315A and operates at a maximum voltage of 1500VDC, making it suitable for grid-tied and off-grid photovoltaic systems. With a short-circuit current rating (SCCR) of 15kA at 1500VDC, it provides critical protection against fault currents in solar installations. Designed for secure screw mounting, the fuse-base accommodates cable lugs ranging from 25 to 240 mm² and features M10 terminal screws requiring a precise torque of 32Nm for optimal electrical contact and safety. Its open design ensures straightforward fuse link insertion and removal, simplifying maintenance and reducing downtime in solar power systems. Compliance with RoHS standards confirms the absence of hazardous substances, while adherence to IEC 60269-6 and UL 2579 specifications guarantees compatibility with international safety and performance requirements. The Mersen C1037509 is part of the HelioProtection® product range, a dedicated line of photovoltaic protection solutions designed to enhance system reliability and longevity in demanding solar energy environments.
